BUTTON -MAKING MACHINE.

Specification of Letters Patent.

Patented Sept. 21, 1909.

Original application filed March 3, 1904, Serial No. 196,270. Divided and this application filed October To all whom it may concern:

Serial No. 397,981.

Be it known that I, EDGAR SHANTZ, 0f Rochester, in the county of Monroe, in the State of New York, have invented a certain new and useful Button-Making Machine, of

which the following is a specification.

My invention has for its object the production of a button-making machine for simultaneously forming and securing shanks or stems to button-heads or blanks, and it con- 4 sists in the combinations and constructions hereinafter set forth and pointed out in the claims.

The drawing is a sectional view, partly in elevation, of my machine, non-essential parts being omitted.

Buttons having heads or blanks formed of pearl, or other fragile substances, are usually provided with metallic shanks or stems' in the manufacture of such buttons, the shanks or stems have heretofore been secured to the heads by expansion of the metal forming the shanks.

To those skilled in the art, it is well known that when button-heads and shanks are united, as described, a large percentage of the heads is destroyed by breakage, even though slight expanding strain is used, and

that the shanks are but insecurely fastened v to the heads, and frequently become detached therefrom. especially when in use and subjected to strain, thus rendering the buttons objectionable and tending to decrease the use thereof. By this invention, buttons of the described type are provided with shanks which resist to a maximum any strain tending to detach the same. A button constructed bythis machine, is shown .in my pending application, Sr. N 0. 196,270,

of which this part.

A is a movable die or mold formed with mold-cavities a extending through opposite portions thereof said die or mold being thus provided with inlet and exit orifices. B B are recessed button-heads or blanks which are presented to the mold-cavities a with their recesses b opposed to the exit orifices of the mold-cavities a. These button-heads B are received in sockets a formed in the die or mold A and communicating with the exit orifices of the mold-cavities a, and said heads are supported in the sockets (1', especially during the formation of the cast shanks or stems, by a plate or plunger 0 which is proapplication is a divisional vided with a stem 0 guided in a stationary bearing 0 and encircled by a spring 0 and acts to firmly press the button-heads or blanks B into the sockets a and against the contiguous surfaces of the die or mold A.

is 'a reservoir or melting pot containing fluid material, as molten metal, and also a cylinder cl communicating with the interior of the reservoir and with an outlet conduit or port d extending from the base of the cylinder (Z through a surface of the reservoir opposed to the face of the die or mold A through which the inlet openings or orifices of the mold-cavities ja extend. Said face of the die or mold A f brms means for closing the exit of the reseryoir D. A suitable piston d? ismovable in the cylinder 03 for compressing the fluid material therein. The rcservolr D is provided with a depending arm (Z which supports a plunger (Z movable cndwise atsubstantially right-angles to the die or mold A, into the mold-cavities a for discharging the finished button.

The die or mold A is movable into position to aline the gate orinlet orifice of one of its mold-cavities wwith the exit of the conduit (5, and is then stopped, whereupon the piston (Z is moved toward the bottom of' the cylinder (1 and forces the molten material under pressure from the conduit cl into said mold-cavity and the recess b in the button-head B in register therewith. After the entry of the molten material to said mold cavity, the piston (l is reversely moved, withdrawing the molten metal from the conduit rl into the cylinder (Z. The die or mold A is. then advanced to aline the gate or inlet orifice of a second mold-cavity a with the exit of the conduit (5', after which the molten n'ietal or material is forced into this second mold-cavity and the recess 6 in register therewith, and then the die or mold A is again advanced. As the die or mold A advances step by step, it feeds beyond the plate or plunger C, one of the mold-cavities containing a cast stem or shank and alines said stem with the plunger 03*,

after which said plunger is actuated and discharges the button from the die or mold A.

As anysuitable means may be used for moving the die or mold into operative position and for actuating the piston (l and the plunger (1*, I have deemed it unnecessary to illustrate and describe such mechanism.
